Four Kinds Of Interaction Between Krishna And Arjuna

“Although Krishna is manifested before Arjuna in His universal form, Arjuna remembers his friendly relationship with Krishna and is therefore asking pardon and requesting Him to excuse him for the many informal gestures which arise out of friendship. He is admitting that formerly he did not know that Krishna could assume such a universal form, although He explained it as his intimate friend.” (Shrila Prabhupada, Bhagavad-gita, 11.41-42 Purport)
